我试图在pandas中的一列上使用一个简单的.apply函数,这导致了这个错误。很快需要帮助。这是我的第一个问题,请忽略我的编辑和结构问题。
data = {'A':[1, 2, 3],
'B':[4, 5, 6],
'C':[7, 8, 9] }
df = pd.DataFrame(data)
df['add'] = df.apply(lambda row : row['A'] + row['B'] + row['C'], axis = 1)
我在Pandas中的任何简单.apply((函数中都会遇到这个错误。列上的任何应用程序((都会导致此问题。

当我尝试在azure-databricks
集群上运行它时,由于集群管理问题而出现此问题。
清除状态并再次运行解决了问题。
_mgr
通常是一个集群/编译器管理器问题。
